Which statement regarding the location of the stomach is false?

The stomach is indeed located primarily on the left side of the abdomen, which makes the statement about it being on the right side inaccurate. Specifically, the stomach's position is usually described as being situated inferior to the diaphragm and lateral to the midline, predominantly residing in the upper left quadrant.

It is also correct that the stomach plays a significant role in both mechanical and chemical digestion, breaking down food through physical processes and enzymatic reactions. Therefore, the false statement highlights a misunderstanding of the actual anatomical location of the stomach within the human body.
